 I use Icaros (https://github.com/Xanashi/Icaros) for thumbnail generation
 in Windows 11. It uses ffmpeg for that. Icaros has trouble with some jp2
 files. I reported the issue here: jp2 support #108
 (https://github.com/Xanashi/Icaros/issues/108) and got a response that it
 is ffmpeg's fault.

 I reported the issue here again: jp2 support #152
 (https://github.com/GyanD/codexffmpeg/issues/152) and got a responce that
 it is the file's fault:
 SOC marker not present
 error during processing marker segment ff55

 However, there are many jp2 files on archive.org website with the same
 issue. XnViewMP and IrfanView can show the files OK. So, may be the errors
 are not severe and ffmpeg could just treat the errors as warnings and move
 on?

 Here are two sample files, for which, I get black thumbnails:
 1) https://archive.org/download/dr_pratts-high-test-plan-of-the-eastern-
 counties-and-the-midlands-12471000/12471000.jp2
 2) Attached "test file.zip". It is a scan of an empty white page.

 Can you please have a look?
